Be it known-that I, PERCY. HLEYOUiNQ'fl of v.lviassachusetts, have ;invented an Im- 'prov ement in'VVoodworking Machines, of ,which the following description, inconnec- ;tion ,with the accompanying drawings, is a specification,- like: characters on the drawings l representing like parts.

This invention relates to wood working .machines and inparticular to the construction of the side leg and associated mechanism of a matcher or-profiler, that is, to the cutter; mechanism mounted on a more or less upright'axis ;to operate on the edge ofa If board passing through the .machine.

ticular mechanism here shown and "various claim as my invention will be more particularlypointed out. in the appendedclaimsa shown in Fig. 2, maybe. r'zounted on a car- To provide for the'various movements/of the side leg-the motor casing 14, as best- 5 trier plate 16 On which it may, if desired, be

vertically adjusted by'mechanism 18 of well known type.' The carrier '16 is mounted, conveniently in the manner hereinafter described, on a carriage "20 adapted to slide transversely of the machine.- on a guideway 22. Movement of the carriagezon the guidewaywilheifect an in andout adjustment of the side leg.

ment of .the side leg it is mounted pivotally on the carriage 20 and animpor'tant feature of-myinvention consists in the mounting of side leg of a matcheror like. machine in such a manner that it may be angularly ad-= justed about a center located in the plane To permit a swingin w of the work support as 10. 1 By such aconstructionthe cutter head may be adjusted angularly in desired mannerto operate on the edge of the board without the-necessity;

for vertical or other adjustment as the." angle ischanged. 1 t

which point is located substantially at the intersection of the-plane defined by the work support 10; and the plane tangent to the cutter-head interiorly thereof andiin which the cutting operation is performed. It will be understood that this point :24 may move Referringmore particularly to Fig. 3,-the carrier 16 is. here mounted on. the carriage .20-to swing about a. point-24 as a/center, a rotary cutter. head 12 directly driven by.

. point 24 with which cooperates a downwardly facing V hook shaped rib 28, best shown inFi'g's. 2 and 5, by which the carrier 16 is suspended on the carriage'20 in such a manner that it may swing thereon about the point 24 as a center as 28 is moved along 26.

Suitable means are provided whereby the side leg may be held either against swinging movement .or in and out translative move- .ment. Referring to Flgs. 2 and 4 I Wlll first describe themeans whereby the carrier plate 16is clamped to the carriage to prevent rotative f movement. Ihave here shown a screw 30 tapped into plate 16 and loosely receiving a chock block 32 presented adjacent with'tbe carriage as a unit and not be caan edge of the carriage 16, set'screws'34 being provided for positioning the block. Mounted on the screw 30'is a cam 36 pro- ;vided with a hand lever 38 whereby screw and cam can be rotated in such a manner as .to press the chock 32 inwardly against the margin ofthe carriage 20 as in Fig. 2 where by to. clamp the carrier 16 andconsequently the side leg so that the side leg will move pable of rotative movement relatively thereto. For locking the carriage 20 to the guide 22 to preclude translative movement of the side head I may provide a locking rod 40 (best shown in Figs. '2 and 4) having I squared endextending from the side of the illustrated.

or slabbed off as shown at 46 in Fig. 4 and machine by which it may be turned, this locking rod being received between the lower margin of the guideway 22 and the I opposed surface of a bracket 42 which extends rearwardly from the carriage 20, the rod'being held in position by a clip 44 as The rod has one side flattened move? as one therewith;

A single adjusting mechanism is provided which will serve either to move the side leg in and out or to swing it'accordingly as whetherone or the other of the Cooperating clamping mechanisms is in use. For this purpose a suitable traversing means such as an adjusting screw is connected to the side leg itself at apoint remote from the pivot. This idea, as'l have pointed out, is broadly not; original with me but the mechanism here shown including the clamping elements are my invention. It will be clearly understood that if the side leg is held against translative movement it is free to swingabout point 24 and movement of the adjusting device will cause .it to swing about its pivot. If, on the other hand, such pivotal movement is prevented, the same force will't'endto move the leg bodily. The device inthe present instance takes the form of a screw 50 journalled in the frame of the machine and having an operating portion such as the squared end shown projecting at the side thereof. The mechanism is best shown in Figs. 4 and 5, where there is illustrated cooperatingwith the screw a nut 52 which is mounted to slide in an undercut guide 54 in the carriage 20 and has projecting therefrom a pin 56 ex tending from the face of the carriage and entering a radial slot 58in the carrier plate 16, the slot 58 being radial to the center '24 and thus transverse, as shown in Fig. 2, to

the guideway 54 which receives the nut.

Referring to Fig. 2, if we assume the clamping bar 40 to be in position to lock the carriage 20 on the guide 22 and the clamping chock 36 to be released, permitting the carrier 16 to swing on the carriage 20 about the arcuate support 26, if theadjusting'screw 50 is then turned the nut 52 will be moved in its guides 54, say towards the reader viewing Fig. 2, and the pin 56 acting on the walls of'the slot 58 will swing the side leg to the position shown in Fig. 3. On the other hand, if the clamp 40 is released and the clamp 32 thrown in, as in Fig.2, locking of the carrier 16 to the carriage 20 will prevent the nut 52 from moving in the guideway since" it will be locked by engagement of the pin 56 in the slot 58 as will clearly be understood from Fig." Therefore, rotation of the.

screw 50 will move the nut and with it. the

carriage 20 and the side leg will be moved bodily in andout along the guideway 22.

This construction prov-ides for a convenient gage or index of the angular position of the cuttersince angular adjustment of the side leg is effected by movement of the nut 52 in the guides 54. Referring to Fig, 4, there is carried by the nut a rod 60 projecting laterally and cooperating with an index or pointer 62 carried by the edge of the carriage 20j Suitable graduation marks on the rod 16 will give a conveniently read indication of the position of the nut 52 and consequently of the angular adjustment of the leg.

Thus in a given instance the parts may be proportioned to provide for a'movem'ent of 309 on' one side of the vertical and 15 on the other side. The set screw 62 by which the rod 60 is secured permits properplacing of the zero pointthereof.

The arrangement of'the leg to swing about the center 24 facilitates the adjustment as thus force applied-through pin.56 works with a relatively long lever arm.

Referring to Fig. 3, a'suitable bracket 64 larlywith the side leg. In the present instance I have shown it as formed on the motorcasing: This bracket provides a support for a jointer 66 which may be brought-"into cooperation with the'cutter head in any po-" sition of adjustment of the side leg. Thus the cutt'er may be sharpened at'any time without disturbing its angular adjustment.

I believe that I am the first to provide for jointing a side'headafter its adjustment to an ular position in this manner.

eferrin'g to Fig.1, I will next-describe the construction ,of the chip breakerthere shown. This embodies, a generally V U- shaped member exteriorly embracing the side head, one arm of the U being pivoted to fixed point 68. The U is made in two portions' and has the pin and slot adjustment 70 in the base thereof. The other leg 72 of the U forms the chi breaker proper and projects inwardly an bears against the side of the board adjacent the cutter head 12. A suitable stop 7 1 cooperating with the side of the machine prevents the arm 72 from swinging in too far and from being carried in into contact with the cutter head 12'.

To press the chip breaker in against the work means are provided tending to swing it bodily counterclockwise about the pivot 68. Herein an abutment 76 on the base'of the U thrusts against a rod 7 8 carrying a nut 80 which works against thespring 82 interposed between this nut and the upright member 84, best shown in Fig. 2. The member 84: is connected by a link 86 to bracket 88 projecting from the frame of the machine and by the link 90'to the pivot pin 68, this connection being made, as shown in Fig. 1, by an open hook on the link 90 for a purpose hereinafter described. Viewing Fig. 1, it will be seen that if the arm 72 of the chip breaker is pushed clockwise by the work, the whole U-shaped frame will swing about the pivot 68 and the rod 78 will be thrust to the left through member 84 compressing the spring 82. The chip breaker is thus held by spring tension against the work and all the parts are very simply organized around the cutter head on the top of the frame of the machine, being connected thereto by the single pivot 68 andthe simple connection at the bracket 88. The upright member 84; may be provided with an upwardly extending handle 92, as best shown'in Fig. 2, by means of which it may.

be pressed to the right viewing Fig. 1,'so that the link 90 maybe swung free from pivot 68. The tension on the chip breaker through the spring 82 is then released and the chip breaker may then be swung bodily about the pivot point 68 in a clockwise di rection. The force of the spring which would otherwise resist this action is exerted in swinging link outwardly, this being permitted by the-disengagement of the link 90 and no substantial resistance is presented I to the movement of-the' chip breaker..-

'Direct driven cutter heads of the type here shown turn very readily onf theirbearings and there is thus a marked tendencyfor, them to spin 'after'the current has been'cutoff from the motor I find it convenient,"

therefore, to provide a simple mechanism for bringing thefrotat'ionof the heads to a stop. "Referring tov Fig. 4, I have there shown a brake shoe 94 preferably in the form of aplug or red of woodloosely received ina suitableopening'" 'in' t he motor casing and adapted to be thrust upwardly against a disc 96 mounted on the rotor of the motor by means of the pivoted handle 98. c
